Don't go on holiday - that's the ticket for avoiding post holiday blues. Though you get the "my friend is in Spain this week but I was feeling a bit short and didn't join him" blues instead.
Tried beer,just makes me think about being on a lounger next to a pool having a large cool one
Have already started planning next years hols just makes me start the countdown
Before I had dogs I used to love holidays abroad, either skiing or in the sun (although the ones in the sun used to bore me after I'd done the paragliding 4x4 expeditions etc).
These days I'd much rather stay in the UK and take the muts with me and find I'm far more relaxed at the end of the holiday.
